Section 7: Maintenance 51
Pro/Pro-L Card Printer UserÕs Manual
IMPORTANT! 1. Never use a sharp tool or abrasive object of any kind to clean the printhead. You
will damage the printhead!
2. Watches, rings, bracelets, and other jewelry can damage the printhead if
accidentally bumped against it. For best results, remove such items before touching
any internal components of printer.
3. As with any electronic device, internal components of the printer, such as the
printhead, may be damaged if exposed to static electrical discharges. To avoid
potential damage, always wear an appropriate personal grounding device, such as a
wrist strap (with integral resistor) connected to an ESD ground. Or, at a
minimum, make positive contact with the bare metal chassis of the printer with
your hand prior to touching any internal electrical components.
B. STANDARD PRINTHEAD CLEANING
This procedure should be performed if you notice a streak on the card where color
was not transferred. This procedure should also be performed during every ribbon
change or after every 250 prints in order to maintain consistent print quality. The
printhead is located near the center of the opened Top Cover assembly.
1. Open the printerÕs top-right cover by pressing its Cover Release Button.
2. If you observe dust and/or other particles laying on the top surface of the
ribbon, manually roll it up into the take-up roll. Occasionally, dust may settle
on the top surface of the ribbon and cause print quality problems.
3. Use a Printhead Cleaning Pen from the Printer Cleaning Kit or a soft, lint-free
cloth slightly moistened with isopropyl alcohol to wipe dust and other
accumulated particles off the surface of the printhead. If using a cloth, be
extremely careful not to use too much alcohol. It must not be allowed to drip
into the printer!
4. Once the printhead is completely dry, shut the cover. If a streak persists,
perform the steps in Part C.
C. EXPANDED PRINTHEAD CLEANING
Perform if you have a streak on the printed output that canÕt be solved by the
Standard Printhead Cleaning procedure. To maintain your printerÕs high quality of
printing, this procedure should also be performed approximately every 2,500 prints
as part of the printerÕs general maintenance program.
1. Open the printerÕs top-right cover by pressing its Cover Release Button.
2. Use a soft, lint-free cloth slightly moistened with acetone to wipe off the
surface of the printhead. Be extremely careful not to use too much acetone. It
must not be allowed to drip into the printer!
